Hobo Spiders (Tegenaria agrestis) are brown and measure roughly 12 to 18 mm in length. Their legs show no distinct rings and have short hairs. Their abdomens have several chevron shaped markings. Males are distinctively different from females in that they have two large palps that look like boxing gloves. These palps are often mistaken for fangs or venom sacs, but they are in fact the male genitalia. The females also have these palps, but the ends are not 'swollen' as they are on the males. Females tend to have a larger and rounder abdomen when compared to males.
The Hobo Spider aka as the Aggressive House Spider, has been suspected of presiding in the United States as early as the 1920's and 1930's. Originally from Europe, the Hobo Spider is a species foreign to the United States. They are believed to have been transported to the United States via shipping lanes and ended up in Seattle, Washington. Since then they have slowly expanded throughout the Northwestern United States and Western Canada.
